In the previous post, I’ve started going through LDA e4 FPGA board enclosure features that are most popular with FPGA users.
Next items on the list are:
- Runtime fan control.
Another significant feature introduced in LDA e4 FPGA board enclosure is the dynamic and controllable cooling system. The fan controller adjusts the fan speed based on FPGA board power consumption, SFP module temperature, and several other input parameters. The thresholds are fully configurable via User Interface. And you can (almost) silence the fans if the device sits on your desk until the system starts running hot!
- High-accuracy clock source
LDA e4 FPGA board enclosure provides an optional 10 ppb clock generator. It can serve as a replacement for PCI Express (PCIe) reference clock which means no external reference clock port is required. If PCIe core is not needed, you can configure the clock to any frequency up to 350 MHz. It is a helpful feature for the boards with fixed and low-cost clocking resources.High accuracy clock source also allows the IP cores that run on LDA e4 to have precise timestamping and related functionality which will work even in data centers that don’t have GPS connectivity.
- Code portability.
Fully generic x86_64 platform and support for virtually any FPGA board allow using already existing IP Cores and associated software: PCIe-based or standalone, practically without any modifications.
- Customizable and flexible software environment
Based on your software needs you can choose both the OS to install on the motherboard and the motherboard itself depending on how powerful a processor you want. And, by chance, if your FPGA board does not communicate with the system via PCIe and you don’t need a PCIe connection at all, you can just skip this: LDA e4 FPGA board enclosure doesn’t need a motherboard to be a fully functional standalone device.
Two features that do not strictly affect FPGA programming, but their popularity with the users puts them on the spot and prompts me to include them on the list.
- No cabling.
A feature highly appreciated by network administrators and anybody who has to deal with high-speed cabling. No more dealing with octopus cables, no more stopping all 10G links in the QSFP port when you only need to unplug one. LDA e4 FPGA board enclosure turns this:
And it is internal too!
And last, but not the least:
- 25Gb Ethernet support
Not a lot of alternatives to this one yet.
In the end, I would suggest that if you haven’t done it before, you should go here and read about LDA e4 FPGA board enclosure and its main features such as PCIe repurposing, Layer 1 replication, etc. This list was rather an engineer’s pick on its bells and whistles.
This device is robust, fast, scalable and well on its way to becoming the leading platform not only for developing IP cores but also for delivering them.
